Pour poblano mixture into hot oil and cook sauce for 5 minutes, stirring constantly. Add remaining chicken stock, rice, and salt. Bring to a boil. Reduce heat and simmer 15 to 20 minutes or until rice is tender. Add chicken and cream; heat thoroughly. Place heaping tablespoon cubed cheese in bottom of each bowl. Ladle soup over cheese and serve immediately. *Recipe based on regular-milled long grain white rice. If using other types of rice refer to rice cooking chart.
